American Bass XD2000 Reviews please!

I am almost about to click, "Pay Now" on this American Bass XD2000 but I want to know some experiences and REAL numbers on a 14 volt system, atm I have a 250A alt and a nsb and a yellow top, big 3 and am runing multiple runs of 0...

Any experiences, I search on termpro a little and searched here and found nothing, only thing I found is this and IDK to believe it, I understand what it is rated at but I want realistic, amperage draw and things of that nature, please discuss...
